The officially validated plane width limit is 4k on skl+, however we already had people using 5k displays before we started to enforce the limit. Also it seems Windows allows 5k resolutions as well (though not sure if they do it with one plane or two). According to hw folks 5k should work with the possible exception of the following features: - Ytile (already limited to 4k) - FP16 (already limited to 4k) - render compression (already limited to 4k) - KVMR sprite and cursor (don't care) - horizontal panning (need to verify this) - pipe and plane scaling (need to verify this) So apart from last two items on that list we are already fine. We should really verify what happens with those last two items but I don't have a 5k display on hand atm so it'll have to wait. In the meantime let's just bump the limit back up to 5k since several users have already been using it without apparent issues. At least we'll be no worse off than we were prior to lowering the limits. Cc: stable@vger.kernel.org Cc: Sean Paul <sean@poorly.run> Cc: José Roberto de Souza <jose.souza@intel.com> Tested-by:

The MCC hpd table is just a subset of the ICP table; we can eliminate it and use the ICP table everywhere. The extra pins in the table won't be a problem for MCC since we still supply an appropriate hotplug trigger mask anywhere the pin table is used.

We generally assume future platforms will inherit the behavior of the most recent platforms, so update our DDC pin mapping defaults to match how ICP/TGP behave (i.e., pins starting from GMBUS_PIN_1_BXT for combo PHY's and pins starting from GMBUS_PIN_9_TC1_ICP for TC PHY's). MCC's non-standard handling of combo PHY C seems like a platform-specific quirk that is unlikely to be duplicated on future platforms, so continue handling it as a special case. Without this change, future platforms would default to gen4-style pin mapping which is almost certainly not what we'll want. Cc: José Roberto de Souza <jose.souza@intel.com> Signed-off-by:

When using virtual engines, the rq->engine is not stable until we hold the engine->active.lock (as the virtual engine may be exchanged with the sibling). Since commit 22b7a426 ("drm/i915/execlists: Preempt-to-busy") we may retire a request concurrently with resubmitting it to HW, we need to be extra careful to verify we are holding the correct lock for the request's active list.

Our assumption that the we can ask the HW to lock the SFC even if not currently in use does not match the HW commitment. The expectation from the HW is that SW will not try to lock the SFC if the engine is not using it and if we do that the behavior is undefined; on ICL the HW ends up to returning the ack and ignoring our lock request, but this is not guaranteed and we shouldn't expect it going forward. Also, failing to get the ack while the SFC is in use means that we can't cleanly reset it, so fail the engine reset in that scenario. v2: drop rmw change, keep the log as debug and handle failure (Chris), improve comments (Tvrtko).

A few times in CI, we have detected a GPU hang on our Haswell GT2 systems with the characteristic IPEHR of 0x780c0000. When the PSMI w/a was first introducted, it was applied to all Haswell, but later on we found an erratum that supposedly restricted the issue to GT1 and so constrained it only be applied on GT1.

Stop setting ->pipe_mask to zero when display is disabled, allowing us to have different code paths for not actually having display hardware, and having display hardware disabled. This lets us develop those two avenues independently. There are no functional changes for when there is no display. However, all uses of for_each_pipe() and for_each_pipe_masked() will start running for the disabled display case. Put one of the more significant ones behind checks for INTEL_DISPLAY_ENABLED(), otherwise the cases should not be hit with disabled display, or they seem benign. Fingers crossed. All in all, this might not be the ideal solution. In fact we may have had something along the lines of this in the past, but we ended up conflating the two cases. Possibly even by recommendation by yours truly; I did not dare dig up that part of the history. But the perfect is the enemy of the good, this is a straightforward change, and lets us get actual work done in both fronts without interfering with each other.

Prepare for making a distinction between not having display and having disabled display. Add INTEL_DISPLAY_ENABLED() and use it where HAS_DISPLAY() is used after intel_device_info_runtime_init(). This is initially duplication, as disabling display still leads to ->pipe_mask = 0 and HAS_DISPLAY() being false. Note that ever since i915.display_disable was introduced, it has not affected PCH detection even if it uses HAS_DISPLAY(), as display disable happens after that. Since INTEL_DISPLAY_ENABLED() will not make sense unless HAS_DISPLAY() is true, include a warning for catching misuses making decisions on INTEL_DISPLAY_ENABLED() when HAS_DISPLAY() is false. v2: Remove INTEL_DISPLAY_ENABLED() check from intel_detect_pch() (Chris) Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

Since d0aa694b ("drm/i915/pmu: Always sample an active ringbuffer") the cost of sampling the engine state on execlists platforms became a little bit higher when both engine busyness and one of the wait states are being monitored. (Previously the busyness sampling on legacy platforms was done via seqno comparison so there was no cost of mmio read.) We can avoid that by skipping busyness sampling when engine supports software busy stats and so avoid the cost of potential mmio read and sample accumulation. Signed-off-by:

Reuse the same .modeset_calc_cdclk() function for all bxt+. The only difference in between the cnl/icl and the bxt variants is the call to cnl_compute_min_voltage_level(). We can do that call just fine on older platforms since they leave min_voltage_level[] zeroed. Let's rename the function to bxt_compute_min_voltage_level() just so it stays consistent with the rest of the naming scheme. Signed-off-by:

We're forgetting to mask off all three pipe select bits from the CDCLK_CTL value on icl+ which may lead to the extra bit being left in. That will cause us to consider the current hardware cdclk state as invalid, and we proceed to sanitize it even though the hardware may have active pipes and whatnot. Fix up the mask so we get rid of all three pipe select bits and thus hopefully no longer sanitize cdclk when it's already correctly programmed.
